Description

Technical Field

[0001] This utility model relates to the field of antenna testing technology, specifically to a phased array antenna testing device. Background Technology

[0002] As the most critical component of phased array radar, the phased array antenna is an antenna system that achieves electronic beam steering by adjusting the phase and amplitude of the radiating elements in the array. It consists of an antenna array, a feed network, and a beam controller, where multiple radiating elements can share a single phase shifter to form a subarray combination. By using the phase shifter to change the maximum beam pointing, it can quickly complete beam scanning and tracking, covering a ±60° conical scanning area, and reduces sidelobes through density weighting technology. According to the technical architecture, it is divided into passive phased array (PESA) and active phased array (AESA). The former uses a centralized transmitter, while the latter equips each antenna element with an independent T / R module, supporting multi-beam generation and anti-jamming capabilities.

[0003] To comprehensively evaluate its performance, testing is required at different angles and heights to ensure good performance in all directions. Currently, existing phased array antenna testing devices primarily rely on multi-person collaborative adjustments. When adjusting the angle and height of the phased array antenna, multiple people lift the tail of the testing device and use padding blocks for fixation. This method involves high workload for operators and poses a safety hazard of slippage.

[0004] Therefore, it is essential to design a phased array antenna testing device to facilitate the testing of the phased array antenna at different angles and heights in order to comprehensively evaluate the antenna's performance. Summary of the Invention

[0005] This invention aims to solve the technical problem that existing phased array antenna testing devices are inconvenient for adjusting the angle and height of the phased array antenna. The purpose is to provide a phased array antenna testing device that enables the adjustment and fixation of the tilt angle and height of the phased array antenna, facilitating more stable antenna performance testing, and offering high adjustability and simple and convenient operation.

[0006] This utility model is achieved through the following technical solution.

[0007] A phased array antenna testing device, comprising: Support base; An antenna mounting bracket is rotatably connected to a support base via a rotating structure, and a phased array antenna body is mounted on one end of the antenna mounting bracket. A sliding counterweight structure is installed at the other end of the antenna mounting bracket, including a counterweight block, which causes the antenna mounting bracket to rotate about the connection point of the rotating structure by sliding.

[0008] Furthermore, the sliding counterweight structure includes a slide rod and a guide rail. The slide rod is fixedly connected to the other end of the antenna mounting bracket, the guide rail is mounted on the slide rod, and the counterweight is slidably connected to the guide rail.

[0009] Furthermore, the guide rail has several positioning grooves spaced apart on its side, and the inner wall of the counterweight has several retaining rings spaced apart to cooperate with the positioning grooves, and the retaining rings have sliding grooves.

[0010] Furthermore, the rotating structure includes a load-bearing block fixed to the surface of the antenna mounting bracket, and the load-bearing block is rotatably connected to the support base via a rotating shaft.

[0011] Furthermore, the load-bearing support block includes a lower load-bearing support block and an upper load-bearing support block, both of which have slots that match the surface of the antenna mounting bracket.

[0012] Furthermore, the lower and upper load-bearing blocks are locked and fixed by screws.

[0013] Furthermore, the side of the support base is provided with a limiting guide structure at the end of the rotating shaft. The limiting guide structure includes a limiting disc and a limiting rod. The limiting disc is fixed to the end of the rotating shaft, and an arc-shaped limiting groove is opened on the limiting disc. The limiting rod passes through the limiting groove and is fixed to the side of the support base.

[0014] Furthermore, the limiting disk has a fan-shaped structure.

[0015] Furthermore, the support base is an L-shaped mounting plate arranged opposite to each other.

[0016] Furthermore, each end face of the antenna mounting bracket is provided with several connection holes for connecting to the phased array antenna body and the sliding counterweight structure.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. When using the testing device of this utility model, the position of the sliding counterweight relative to the connection point of the rotating structure changes. Due to the change in the lever arm on one side of the fulcrum, according to the principle of torque balance, the antenna mounting bracket can rotate around the connection point of the rotating structure, thereby realizing the rotational movement of the phased array antenna body in the vertical plane. This allows for the adjustment of the phased array antenna at different angles and heights, making it more convenient for testers to adjust the angle and position. It can significantly reduce the workload of operators, requiring only one operator to perform antenna testing operations. It features high adjustment efficiency and ease of use. 2. In this utility model, the sliding groove and positioning groove of the counterweight block cooperate to allow the counterweight block to slide linearly along the sliding rod. When it slides to the required position, the counterweight block is rotated so that the retaining ring inside the counterweight block is engaged in the positioning groove of the guide rail, thereby limiting the front and rear positions of the counterweight block. This fixes the relative position of the counterweight block on the sliding rod, thus fixing the angle and height of the phased array antenna and making the adjustment operation simple and convenient.

[0026] Example 1

[0027] This embodiment provides a phased array antenna testing device, such as... Figures 1-5 As shown, it includes: Support base 2; the support base 2 is an L-shaped mounting plate arranged opposite to it; The antenna mounting bracket 3 is rotatably connected to the support base 2 via the rotating structure 4. A phased array antenna body 1 is mounted on one end of the antenna mounting bracket 3. Several connection holes are opened on both ends of the antenna mounting bracket 3 for connecting to the phased array antenna body 1 and the sliding counterweight structure, respectively. A sliding counterweight structure is installed at the other end of the antenna mounting bracket 3, including a counterweight block 8. The counterweight block 8 causes the antenna mounting bracket 3 to rotate around the connection point of the rotating structure 4 by sliding.

[0028] When using the testing device of this utility model, the position of the sliding counterweight 8 relative to the connection point of the rotating structure 4 changes. Due to the change in the lever arm on one side of the fulcrum, according to the principle of torque balance, the antenna mounting bracket 3 can rotate around the connection point of the rotating structure 4, thereby realizing the rotational movement of the phased array antenna body 1 in the vertical plane. This allows for the adjustment of the phased array antenna at different angles and heights, making it more convenient for testers to adjust the angle and position. It can significantly reduce the workload of operators, requiring only one operator to perform antenna testing operations. It features high adjustment efficiency and ease of use.

[0029] See Figure 1 , 4 5. The sliding counterweight structure includes a slide rod 6 and a guide rail 7. The slide rod 6 is fixedly connected to the other end of the antenna mounting bracket 3. The guide rail 7 is installed on the slide rod 6. The counterweight block 8 is slidably connected to the guide rail 7.

[0030] Specifically, the guide rail 7 has several positioning grooves 701 spaced apart on its side, and the inner wall of the counterweight 8 has several retaining rings 801 spaced apart to cooperate with the positioning grooves 701. The retaining rings 801 have sliding grooves 802.

[0031] When the phased array antenna body 1 needs to be rotated and adjusted to the required angle and height for testing, the sliding groove 802 and positioning groove 701 of the counterweight 8 cooperate, and the counterweight 8 slides linearly along the sliding rod 6. When it slides to the required position, the counterweight 8 is rotated so that the retaining ring 801 inside the counterweight 8 is engaged in the positioning groove 701 of the guide rail 7, thereby limiting the front and rear positions of the counterweight 8 and fixing the relative position of the counterweight 8 on the sliding rod 6. This fixes the angle and height of the phased array antenna, and the test can begin. After the test is completed, the counterweight 8 is rotated in the opposite direction, and the retaining ring 801 is removed from the positioning groove 701. The counterweight 8 is then placed in a state where it can slide relatively linearly. The counterweight 8 can be slid horizontally along the sliding rod 6 and removed. The phased array antenna body 1 is then disassembled, and the test ends. Therefore, through the connection structure of the counterweight 8 and the sliding rod 6 of this utility model, the sliding adjustment and relative position fixation of the counterweight 8 are realized, and the operation is simple and convenient.

[0032] See Figure 2The rotating structure 4 includes a load-bearing block fixed to the surface of the antenna mounting bracket 3. The load-bearing block is rotatably connected to the support base 2 via a rotating shaft 403. Specifically, the load-bearing block includes a lower load-bearing block 401 and an upper load-bearing block 402. Both the lower load-bearing block 401 and the upper load-bearing block 402 have slots that match the surface of the antenna mounting bracket 3. The lower load-bearing block 401 and the upper load-bearing block 402 are locked and fixed by screws, thereby fixing them at the corresponding positions on the antenna mounting bracket 3.

[0033] In a preferred embodiment, a safety cover plate 404 is fixed above the upper load-bearing block 402 to cover the components below.

[0034] See Figure 1 and Figure 3 The support base 2 is also provided with a limiting guide structure 5 at the end of the rotating shaft 403. The limiting guide structure 5 includes a limiting disk 501 and a limiting rod 503. The limiting disk 501 is fixed to the end of the rotating shaft 403, and an arc-shaped limiting groove 502 is opened on the limiting disk 501. The limiting rod 503 passes through the limiting groove 502 and is fixed to the side of the support base 2. Specifically, the limiting disk 501 is a fan-shaped structure.

[0035] As the rotating shaft 403 rotates the phased array antenna body 1, the rotating shaft 403 will drive the limiting disk 501 to rotate together. One end of the limiting rod 503 is fixed to the side of the support base 2, and the other end passes through the limiting groove 502 of the limiting disk 501, thereby limiting the rotation trajectory and maximum rotation angle of the limiting disk 501.

[0036] Finally, it should be noted that the above specific embodiments are only used to describe the purpose, technical solution, and beneficial effects of this utility model in detail. It should be understood that the above description is only a specific implementation of this utility model and is not intended to limit the protection scope of this utility model. Although this utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or improvements can be made to some or all of the technical features. These modifications, equivalent substitutions, and improvements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
